Today, you can barely tell the difference between Medium and Ultra settings, and there are some people, who think that running less than Ultra is somehow inadequate, and many of them congregate here.
Ignore that kind of snobbery.
A 1060 will be fine, just turn down the Quality a bit.
Check out this video and others like it. You practically need to freeze frame and pixel hunt to tell the difference between adjacent quality levels.
IMO, you need a 1070 mainly for bragging rights, not gameplay.
You know it's funny. You say 1070 is for bragging rights and then tell someone to turn down settings. That my friend is what we call contradiction. It's not bragging rights if it does help you get better visuals and faster speed.
